USB power injector instructions (9volt battery powered) - Epic 4G General

Here are some instructions on how to build a USB power injector. I built one for my old Nokia N810 and it worked. But I threw it away before the sweet devs gave us host mode on the epic. So, I haven't tried it on an epic yet.
I'm not taking credit for this, just sharing the info. And don't blame me if you break your phone.

That's awesome. I'm gonna have to make one now just cause lol

Patch from the fascinate
See this from the XDA portal this morning. It might put you on a path to fixing this issue.

Damn you beat me to it.
Going to try it out when I leave for school this afternoon, but if this is indeed true, I will be beyond furious. The navigation mount's BOX says that when FroYo is released for the Epic, the audio jack will become functional. WTF

I just tried the car_cradle_patch.zip on my phone using CWM, and it put the phone into super slow motion mode when I restarted. I can't do anything, it takes MINUTES for anything to respond. Looks like I'll have to be wiping my phone again.
tw_car_dock.zip added a "car cradle" application, but the music player didn't play out of the line out on the car or desktop docks.
It was built for the Fascinate. Someone would probably have to mod their mod to get it working correctly on the Epic. Try putting a request out there and see if any devs bite. Might take a few days for someone to get to it because I am sure they are working on updating ROMs, etc.
I pulled apart the original and the modded version that were posted and there is literally one line different between the two (assuming I did it right, and I think I did). If it isn't working properly on our phones it's likely something to do with difference between our phone and the Fascinate/standard Galaxy S. Might help if we can get a logcat dump from the phone while the app is doing it's thing.

Sound like it is as simple as changing the audio channel its using. Maybe there is one not listed in the UI that is the usb audio out?
Audio is working with the fascinate mod.
I used cwm earlier today.Just make sure to place the zip in the root of your micro sd card and boot into cwm then select and flash.It is working perfectly with no force quits or lag after a reboot. Are you using the aosp music player patch or samsung music player patch? He has 2 different versions up. The aosp music player patch is the one i was able to use with no errors or lag.If you are using the samsung music player patch that will not work.
So I bought two docks home and car that said it would work with 2.2
Big surprise.......it doesn't. Awesome samsung.
I just spent 2 days dishwasher shopping. spent 800 bucks. guess who was off my list before I even LOOKED at them! That's right, samsung, you didn't even get on the list to start for reasons exactly like this.
Bump for y'all to see rpro95's post.
@ J3ff, if you have nothing constructive to say just hold off on posting as it looks like there are a couple of people in here who are willing to try and get this working or help the Epic users get it working/troubleshoot. I think most people in here are tired of the anti-samsung semantics.
I do not have the dock, but I am just trying to be helpful in this thread by tossing ideas out there. It seems like this is something that, in time, the community should be able to get working.
car dock AOSP audio out fix for music only.
This might work on the home dock as well.test it. I don't have a home dock.I know it works for my car dock.
If you need to have your tunes playing from your car dock do this.It will not work for third party apps.Only for the AOSP music player.You will get a prompt when you dock.Just select and you will get screen showing your dock icons for
phone:Music:Maps and voice search.
1. Need to have cwm to flash this.
2.download the patch from here on xda developers Adrynaylyne mod thread for the fascinate. http://adrynalyne.us/files/patches/car_cradle_patch.zip
3. Put on your SD card. I put mine in root.This worked for me.
4.Boot into cwm. Select zip and enjoy music on your epic through your cars speakers.This might work on the home dock as well.test it. I don't have a home dock.
Here is the solution: http://forum.xda-developers.com/showthread.php?t=966588

What's this now? You can charge your phone from the Xoom????
Well, without any hacks, I can plug a usb host cable in to the xoom, and then plug my standard USB cable in to the Host Cable and and the other side of the standard usb in to my phone. It then charges the phone.
Will also search for the hack bwcorvus refers to.
Glad it works without root. The hack has been pushed into all rooted kernels, so if you download any kernels from the dev section your good.
Its the mount usb drives hack...thumb drives.

Good point.. I should clarify 'without a hack'. I am likely mistaken as I probably am just too ignorant to know what 'hacks' are already built in to the system since I rooted and tiamat kerneled my wifi xoom last week. I just meant no 'additional' hacks today.
Plus my phone is rooted and has the phoenix rom. Sooo.. maybe they are already 'hacked'. So I don't yet know about a 'unrooted xoom' as mine is not.
UPDATE: From my personal perspective, my xoom already had Roebeet's hack. I verified by hoocking up a thumbdrive and the mount was already directed to the /usbdisk folder. What I realized I cannot yet do.. is to copy files from my phone's external sdcard.. to the xoom. Not that I would really need to... plus I could do it over BT if I really needed it.

Usb not responding

Trying to connect my mates epic 4g to the computer over standard usb cable to her acer one netbook. And nothing works. Not in or out of debug mode. Not in all the usb ports. Installed the samsung drivers nothing. all it does is charge it. I'm I missing something here, trying to help someone out. Any help would be great.
Sent from my R800i using XDA App
I have no real answers but I will say that the drivers from Samsung are total trash. I have three different computers I connect to and several different cables. For all three computers I need to frequently re-install the drivers, and each time I do, there's no better than a 50% chance it will work. So, I don't think you're missing anything other than the fact that this is a very common problem with no real solution other than to try another cable if you have one and to try to uninstall and re-install the drivers a couple of times.
Thanks for your help. Just trying a new cable too. Its there anything anyone has done as a foolproof method. After all my nokias, htc and sony ericsson phones, I don't expect this.

Sounds like you have a faulty stock usb cable. Get a replacement from a sprint repair store.
Cheaper and higher quality cables can be found on ebay, amazon, or monoprice. The last place I'd look for replacement cables is at the Sprint store.
I'd second rebooting the phone and your PC, always worked for me in a bind.

Edit: Screen Flashes in download mode when plugged into the usb port. Other then that another night trying and no luck. Anyone know if places "physical stores" offer any higher quality cables. RadioShack, something like that? As I can't buy things over internet in USA atm.
Would a powered USB hub help also? Anyone tried that?

Where did you get yours from?
Yeah I am facing the same problem, worked two days ago and now nothing. going to try the install fo the drivers again and if not working, new cable.
I had the same problem and then I noticed that 2 of the USB pins in the phone's usb port had detached from the center plastic piece and when I connected the cable, they bent and got pushed back. I can still charge but I will never have usb connection again.
Sprint wouldn't take the phone back.
I just use Swiftp like another said.
So I got it to recognize, it shows the usb button, i press it and nothing happens. I downloaded Swiftp, freaking awesome!
I plug in the phone to charge while on the computer and it allows me to connect usb for mass storage. Go figure. I have not changed anything since last night btw.
To those that use swiftftp. Have you tried File Expert? its an all in one file manager
that supports http and ftp access to the SD card, and can host over wifi or 3g/4g
Resurrecting an old thread because my phone suddenly stopped responding to plugging in the USB cable. I have been using the same cable for a couple of years with no problem. I also tried another cable that has worked fine. The phone charges but I get no data connection of any type. No PDAnet and no USB storage device. I tried a couple of computers and rebooted both the phone and the computers. I have to assume it is a hardware issue of some sort.
I happened to edit my build.prop earlier today to stop the update message, but I assume this is unrelated.
Look in the port if there is some gunk in there. Just helped somebody earlier with the same problem. None of us ever close the little door. He used a toothbrush to clean his.

Do I need to floss too, or just brush?
I sprayed it with some CRC electronics cleaner a bit earlier and I am letting it dry. I will give a brushing too.

I got the New Samsung USB connection Kit

I got the New Samsung USB connection Kit today, I have the Galaxy Tab 7 from T-Mobile, and YES I do know that it will not work with the Froyo installed, but I got a great deal on it for $15.00 free shipping, so when the talented XDA people find a way, of which I am confident someone will!. I took some pictures so everyone could see the packaging if you have not already.
Yes I did try it just for fun and of course nothing happened.

you gave us only the first half of the information about the dongle ...the point is: does it work or not???
Hoping to get a response from the poster.
A lot of question had already been posted....it would be great if it really could work.
I do not want to disappoint you all, but my guess is that he orderd this http://www.123cellularsupply.com/products/Samsung-Galaxy-Tab-10.1"-USB-Adapter.html
it is adapter for Galaxy Tab 10.1 ad probably won't work with Galaxy tab
the same as the another great accessory http://samsung.mobilefulfilment.com.au/Products/ViewProduct.aspx?ProductVariantId=EPL-3PHPBEGSTD

[Q] Will USB port will work as a host?

Will usb port work as a host on the Amazon Fire to support USB flash drive, card readers and other USB peripherals? The USB - micro-b port powered would have to be powered...
If it is, it would compensate to some extent for the lack of microSD card slot.
I have my pre-order in and will cancel if the USB port doesn't work on the host.
Hopefully Amazon will release review models soon!
Thanks!
If you've asking if the device can connect to a pc as a mass storage device, I've read that it can but won't know for sure until I get it in my hands.
Reread your question and I don't think it will do that.
sent from my Infuse at Tranquility Base.
What he asked is if it will work as a host - which means if we could attach pendrives and card readers to it. No one knows right now.
I seriously doubt if the port will work as a usb host. Since, it is a micro usb port, you would need an adapter. But that's easy enough to acquire.
If it does have the capability to host, IE hardware. I don't think amazon would code the software side of things. Espy with all the hype of their could service.
I am hearing that the kindle fire can't use USB host support because it wasn't released until 3.1. Then what about the tablets that do support USB host like the skypad. Also amazon is using a custom version of android which very well could support USB host.
i think it will just be an issue of software, and that is fixable with time, i hear that other android builds with the same proc have the drivers so after rooting you may just be able to sideload the driver on and load it up.
i haven't got mine yet or i would already be tring to get this working, it opens up alot of possiblities with this device (more storage, head set, webcam, printer, etc)
i also hear that the wifi module has support for bluetooth, there just isn't a driver, this is also something to look into.
My boss had his fire delivered today. He borrowed the USB OTG cable (adapter from micro to Full Size Female USB) that I use for my Xoom.
We plugged a thumb drive into it and nothing happened.
Time will tell if software can fix this.

Ill save you the trouble ....this MUST be built into the kernel. Amazon would have told us if this was an included feature.
2 options for you guys.
BUY AN ACTUAL ANDROID TABLET AND RETURN THIS...
OR
HAVE SOME PATIENCE!
Do you guys have any idea how annoying it is to be working on something and getting bothered about whether or boy its done yet? All I ask for is patience. Apparently that's too much to ask for!
Us developers are doing all this for free. Donating fuels us.
Ungrateful nerds asking 'Is it done yet?' Just makes us want to say **** all of you and forget it.
Oh and just because someone's name doesn't have 'Recognized Developer' underneath it doesn't mean they aren't a developer.

I understand your frustration, but development has been quiet on here. I think if someone put up they are working o nit and have list of possible features, questions would be quieted.
Either way, if you are working on this, then I am grateful, whether or not you post up what you're doing

I was asking if it was already built in, just wanted to know if it would perhaps work under the correct editions. If you're working on it, great! I just haven't seen any information regarding such.
